Facsimile machine adapted to reduce risk of data loss

1. A facsimile machine with a buffer memory for storing image data received when said facsimile machine is unable to print and an interface to a computer system, comprising: a buffer supervisory means coupled to said buffer memory, for determining how much available space is present in said buffer memory and comparing said available space with at least one threshold value; and a data transfer means coupled to said buffer memory, for automatically transferring received image data from said buffer memory through said interface to said computer system with commands causing said received image data to be stored in said computer system, responsive to the determining and comparing performed by said buffer supervisory means, when said buffer supervisory means determines that said buffer memory does not have more available space than said threshold value.

2. The facsimile machine of claim 1, wherein said data transfer means selects received image data of greatest size in said buffer memory for transfer to said computer system.
